An Asian doctor was forcibly dragged off a plane by air stewards because a flight was overbooked.

Videos taken by shocked passengers on board the United Airlines flight 3411 from Chicago to Louisville show the man being hauled out of his seat.

With his glasses knocked off his face, the stunned medic is dragged backwards down the aisle as outraged passengers voice their disgust.

The flight was overbooked and United had asked for volunteers to leave so that standby aircrew could board. When no one came forward, the airline seemingly decided to take matters into their own hands and decided who was getting off – whether they liked it or not.
